Standout performance

Rockford Fosgate showcases their fanatical commitment to sonic excellence in the Punch Series of speakers, amps, and subs. If you like to listen to potent, powerful music — and feel it too — Punch components will give you impressive sound that'll stand out in a crowd.

Bulletproof bass

Engineers at Rockford Fosgate designed the P2D4-12 12" subwoofer to dish out the kind of powerful low end you crave in your ride. Its responsive paper cone is reinforced with the same Kevlar® fibers used in bulletproof vests so you get the best of both worlds — warm bass that's exceptionally hard-hitting. Rockford Fosgate uses a new technique to attach the oversized rubber surround to the cone that increases available cone area up to 25%, so this sub can push more air for even bigger bass.

Made for heavy excursion

This P2 sub features an extended pole piece and bumped backplate that leaves more room for heavy excursion, so it'll hit deeper lows without "bottoming out." Special venting keeps the copper-clad aluminum voice coils cool through heavy use for consistent bass performance over time.

The dual 4-ohm voice coils allow you to wire the sub for 2-ohm impedance to work with a mono sub amp, or for 8-ohm impedance if you're using multiple subs. The P2D4-12 sub works equally well in a sealed or ported enclosure, so you can choose the kind of bass you want for your system.

To drive this single subwoofer, we recommend a mono amplifier rated between 300 and 600 watts RMS at 2 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Dual 4Ω Voice Coils: The dual 4Ω voice coils offer
wiring flexibility; when wired in parallel the woofer presents a 2Ω load,
when wired in series the woofer presents an 8Ω mono load.

Steel Basket: The P2D4-12 subwoofer features a StampCast steel
basket for added rigidity.

Compression Terminals: The P2D4-12 features spring post
terminals which accommodate speaker wire up to 10 gauge.

CEA-2031 Compliant: Power handling on the P2D4-12 subwoofer
conforms to CEA-2031 industry standards. This means the subwoofer has the capacity
to handle power under continuous demand, not instantaneous power handling, that
over time, can damage voice coils.

Trim Ring: To improve the cosmetic look, a decorative trim
ring is included that mounts over the flange of the woofer. When using the cast
aluminum trim ring the woofer is first mounted with four screws, then the ring
is placed on top of the woofer, aligning the final four holes of the woofer with
ring. The other four screws are used for these holes to mount the ring and woofer
to the enclosure. Without the trim ring the mounting height of the woofer is
just over 7/8 of an inch, with the trim ring it's approximately 1-1/16 inches.
The diameter of the trim ring is 13-5/16 inches.

Enclosure Compatibility

Sealed Box: Rockford recommends a sealed enclosure with
an optimum internal volume of 1.02 cubic feet (from 0.7 to 1.8 cubic feet is
acceptable). Sealed enclosures provide the most control over a woofer, will
handle a lot of power, and provide accurate sonic reproduction, making them
suitable to all types of music.

Ported Box: Rockford recommends a ported enclosure with an
internal volume of 1.79 cubic feet using one 4" diameter x 10" long
port; this yields a tuning frequency of 40 Hz. Ported (or vented) enclosures
typically provide better overall efficiency than sealed so they are suitable
for use with smaller amplifiers, giving you more bass output from less power.
However, this efficiency comes at the expense of very low frequency output
(below 34 Hz).

Rockford Fosgate P2D4 Hits Hard!!

I have this hooked up with a kicker amp pushing 200 watts and this thing can get loud. My system is pushing a total of 1100 watts of power total. My parents always know when I am coming home because they can hear me coming from a mile down the road! This sub is awesome and very loud but don't expect to rattle windows but it you will feel it in the car for sure. I have it in a ported box and there is nothing wrong with it, I have not had any issues with it at all, no over heating or nothing, Great Product, Well done Rockford, Well done.

Surround separated.

Bought this sub about a year ago and had it installed in a 1.0 cu. ft. sealed box pushed by a JL 500v2 amp. After the break-in the sub started to really shine, good bass but I always felt it could be better. Don't get me wrong it's a very good sub I just wanted something that would hit a little harder. I listen to rap, pop, metal, and classical and it did a very good job especially when playing metal. But! After about a year I noticed the bass wasn't as hard and it sounded like something rattling. Looking at it I noticed the rubber surround was starting to separate from the cone. It never got pushed very hard so that left me disappointed. Up until then other than wanting a little more bass, the sub was great. Could have just been a defect because I have had two other RF subs in the past and both worked great.

awesome subs

I have to 12 "p2s in my car they are great subs the dual voice coil gives you lots of options for ohm load and different wireing i have them them set up 2 ohms with 1800 watt amp it sucks more then the amp can give.Ive destroyed a diamod amp and two of these in 2 years, but both we my fault. The first one i didnt know about duel voice coils and only hooked up one side. It worked great for a couple weeks but it made the sub work twice as hard which caused it to smoke and i melted the coil. the other got destroyed from poundng aginsts something in my trunk. After i hooked them up correctly and cleaned my truck they hit hard in cold or hot weather (in colorado we have both sometimes in the same day!) im a firm believe in rockford. had a few different subs over the years and rockford always delivers. increadble lows great high spend a few extra bucks and get these promise you wont be dissapointed

Pros:Sound looks relibility durability over all great sub

Cons:absolutly none as long as you hook up dvc correctly read the manuel with it for different ohm load wiring diagrams

This Subwoofer is one of the Loudest Subs ive bought so far. I had 2 15in P1's and one of these compare to them loud wise. The only thing i dont like about this subwoofer is how warm the coils get after about 30 mins of use. Ive never had a sub run this warm, its not like burning hot but you can feel its getting warm so sooner or later im gonna melt one of the coils. I have a Rockford Fosgate R750.1D Hooked to it running at 2 ohms which the amp is putting out about 500 watts, so it says but i think this amp pushes more then its rated. But still they need to build it better so they dont over heat. For the Money, its worth buying. Very Loud
